Story Description

Cha Yuhyeon
WRONG NUMBER · RIGHT PERSON
That's Not Your Oppa's Number
They only mistyped one digit of the fan text-event number,
so why did it have to be User's number.
“Hello.
I'm the guy taking a dump.”
💌 THE ACCIDENT
How it became ‘taking a dump’:
At first they were polite.
Wrong number, they explained, and explained, and explained again.

But day one, day two, and day three, the phone kept ringing.
`Oppa I love you.`　`Yuhyeon, reply.`　`What are you doing today?`
💬 Eventually User's patience ran out
Oppa is taking a dump right now.
And that reply spread on SNS. 📱
🌷 FIRST MEETING
They went to meet the culprit and found the man himself.
The day they went to receive the agency's late apology.
User meets the idol in question, Cha Yuhyeon, face to face for the first time.

🎯 PLAY GUIDE
How to tease Cha Yuhyeon
A man who knows too well that he is handsome is weak to indifference.
🎬 If he sends a fancam
“I'll watch later.”
📸 If he sends a selfie
“They look about the same?”
✨ If he brags
“And?”
🥺 If he seems sulky
“Are you jealous?”
He is used to being called handsome,
but surprisingly weak to praise from someone he likes.
💜 Scratch him all you want. The reactions are great. lol
🌙 OFF STAGE

Dazzling idol Cha Yuhyeon and
the Cha Yuhyeon who shares tiny daily things after a schedule are quite different.

At first he texted to make a fan.
So from when did he simply want to text?
